EXTENSIBLE SUPPORT.

Application filed January 13, 1915, semi No. 1,978.,

To, all whom it may concern Be it known that I, MYR N S. PELTON, a

citizen of the .United States, residing at Folsom, in the county of Sacramento and .State of California, have invented new and useful Improvements in Extensible,- Supports, of which the following is a specification. v c

This invention relates to an extensible support. i l I The object of the present invention is to provide an extensible support fordrawers, shelves, and the like, in the for'mof a lazy tong structure, whichis m'mple andsubstantial in construction and from which the.

drawers or shelves may be easily and quickly removed for cleaning, renewal or other purposes. 7 a v Further objects of the invention will hereinafter appear. v

The invention consists of the'parts and the construction and combination of parts as hereinafter more fully described and claimed, having'reference to the accompanying drawings, in which Figure 1 is a vertical longitudinal section on line 1.1, Fig. 2. Fig. 2 1s a vertical transverse section on l ne 2-2, Fig. 1. Fig.

3 is a detail perspective view of the connec-- tion formed between the lazy tongs frame and the drawer supporting bar. Fig.4 is a similar yie'w showing the relative position of'the two track bars.

A indicates a suitable support, such as a cured on each side 20f said case or frame filing case, shelf, frame,-or the like.

in a horizontal plane and directly opposite to each other is a pair of angle iron track bars 3 and 4, and extending between said" bars and journaledain their rear ends is a shaft 5 to which is attached the inner'links 7 of a pair of lazy tong frames 6 and 7, there bein one frame ad'acent to each side section 2. The inner lower linkS of each lazy tong frame is secured to shaft 5, while the upper links 9 are turnable thereon. The mounting of the lazy tong frames in this manner causes the frames to move out in unison when they are extended and will thus prevent any side rocking or binding action with relation to the sides of the shelf or drawer carried between the lazy tong frames.

The lazy tongs are, as prevlouslv stated, adapted to support a drawer, shelf or any other suitable article. In the present Specification of Letters Patent.

stance a drawer has been illustrated and Patented Feb. 15, 1 9.11

thisismounted or supported between the lazy tong frames in the followingmann e'r:

Secured on the central pivots lO' and 11 of the lazy tongs, both inside and outside, are; rollers 12 and 13 respectively, and secured to each side of the drawer is a pairof angle lron-trackbars 14 and 15 which areada ted to rest on the rollerslS. The angle bars 14 and 15 are reversed in position. with relation to the bars 3 and 4? and will, therefore,

rest on rollers 13, while angle bars 3 and 4 will serve as supports or tracks for: the rollers 12.

ception of the outer rollers 17. In this manner aconnection. is formed between the lazy tong frame a'nd drawer by which the The outer ends-of the angle bars 14 and} 15 are provided with pockets 1 6 for the retwo will move in unison when pulledin or V out with relation to the main supporting frame A. y Y Y In operation, it is only necessary to. ex-

tend the lazy tong. frames tov the position ers 13 and wherethe .pockets 16 will engage the outer rollers to form the connection preindicated at 18. The drawer is then placed. between said frames in apositionwhere the track bars 14 and 15 will rest upon the rollviously described. The drawer-with connected frames maynow bemoved backinto the mam supportingframe A, causing the lazy tongs to fold up, as'indica tedat C. The connection formed between thelazy tong move in unison, thereby. preventing any bindingiaction at any point. :Theprovision of rollers 12 and 13' furthermore gprevents binding action and permits the drawer to be easily pulled out by meansof a handle The construction involved also permitsthe drawer, shelf, or other device, supported by the lazy tongs to be quicklyremoved or replaced at any time, making the device applicable for many purposes.

The materials and finish of the several .parts of the extensible support are such as the experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that 1' do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what frames by meansofshaft 5 causes these to porting the outer rollers of the lazy tongframes, a drawer disposed between the latter, and an inverted Lrshap'ed traokon each 'side of the drawento' engage WltllilIlCl be supported by theiinner rollers.-

An extensible frame comprising a main supporting frame, a pair of spaced lazy tong frames supported "at their inner ends on the Y main frame, inner rollers mounted on the central and outer end portions of each lazy tong; frame, adrawer arranged between the 20 lazy tong} frames, and an angle iron track secured to each side of the drawer and slidably supported by the central roller of the respective lazy tong frame, the'outer end of each track being formed with a downwardly opening pocket for receiving the outer end roller of the adjacent lazy tong frame.

3. An extensible frame comprlsmg a main supporting frame, a shaft journaled in said frame, a pair of interspaced lazy tong frames supported at the1r inner ends on said 'shaft, one of the'inner links of each lazy tong frame being secured to the shaft and the other link being turnable thereon, inner and outer rollers mounted on the central pivots of the lazy tongframes, a track bar on each side ofthe main supporting frame upon which the outer rollers are guided and supported, and a drawer mounted between the lazy tong framesand supported on the inner rollers. 3
